IMPRESSION-ROLL.

Specification of Letters Patent.

Patented June 19, 1917.

Application filed May 3, 1916. Serial No. 96,952.

To all whom it may concern:

Be it known that we, JAMES W. MoINDoE and ARTHUR E. WHITNEY, citizens ofthe United States of America, and residents of Winchester, in the countyof Middlesex and State of Massachusetts, haveinvented certain new anduseful Improvements in Impression-Rolls, of which the following is aspecification.

This invention relates to impression rolls and mounting therefor andparticularly to rolls of this character adapted to impress into thesurface of a sheet of softmaterial a plurality of indentationswhichmay'beof various depths and thicknesses, and which may beeitherregular or irregular'in formation.

The object of the invention is the produc tion of an impression rollwhich maybe constructed in an inexpensive manner, and which whenfinished will be perfectly cylindrical with a plurality of projectionsex tending outwardly from its periphery.

The invention consists in an impression roll having a thin pliablemetallic sheet formed into a cylinder with a plurality of projections onits periphery and provided with a continuous cylindrical backingv of thesame metal depositedthereon by electrolysis.

The invention further consists of new and improved means for mountingsaid cylinders upon an arbor and removing the same therefrom.

The invention consists further of certain novel features-of constructionand arrangement of parts which will be fully understood by reference tothe description of the drawings and to the claims hereinafter given.

For the purpose of illustrating the invention, one preferred formthereof is illustrated in the drawings, this form having been found togive satisfactory and reliable results, although it is to be understoodthat the various instrumentalities ofwhich the invention consists can bevariously arranged and organized and that the invention is not limitedto the precise arrangement and organization of these instrumentalitiesas herein shown and described.

Of the drawings:

Figure 1 represents a longitudinal section of an impression roll andarbor embodying the principles of the present invention.

Fig. 2 represents an end elevation of the same.

Fig. 3 represents a partial longitudinal section of the same,'showingthe means for {)emoving the impression roll from the ar- Figs. 4 and 5represent enlarged sectional details of a' portion of the outer cylinderwith its cylindrical backing, and

Figs. 6 and '7' represent similar sections having a modified form ofprojections on the periphery thereof.

Similar characters designate like parts throughout the several figuresof the drawings.

In the drawings, 10 is an arbor provided with threaded hubs 11 and 12 inaxial alinement, these hubs 11 and 12 being provided with alinedtrunnions 13 adapted to be mounted in any suitable bearings in which itis desired to rotate said arbor 10.

' The arbor 10 is cone-shaped and provided with-a key-way 14 extendinglongitudinally thereof. Mounted upon the arbor 10 is an impressioncylinder 15 provided with a key 16 formed integral therewith extendinginto the key-way 14 of the arbor.

The impression cylinder consists of an electroplate 17 of thin pliablemetal reinforced'by a cylindrical backing 18 of the same metal, whilewithin this cylindrical backing :18 is another tubular supporting member19, preferably formed of type metal or some other similar softnietalwith its bore cone-shaped to fit the periphery of the arbor 10.

The electroplate 17 is provided with a plurality of projections 20 ofdifferent heights and widths, as indicated in Fig. 4

of the drawings. These projections may be of various lengths, asindicated in Fig. 5 of the drawings.

It is obvious that the projections on the periphery of the electroplatecylinder 17 may be irregular in formation, or have a regular formation,as indicated in Figs. 6 and 7 of the drawings.

The electroplate 17 is first made in a fiat plate and then formed into acylinder with its opposing ends abutting as at 21. This cylinder 17 isthen reinforced with a backing of the same metal deposited thereon byelectrolysis, the backing thus deposited forming a continuous cylinder18 which unites "with the rear face of the electroplate ders rigidity sothat it may be readily handled.

After this shell 1718 has been formed 7 the support 19 is cast thereinwith the key 16 formed on its inner wall. Threaded to the hub 11 is anannular plate 22 having a ring 23 mounted in a depression on its innerface. A similar collar 24 isv threaded to the hub 12 and this collar 24has a ring 25 mounted in a depression on its inner face. The'eollar'24has a plurality of threaded members 26'inounted therein bearing againstthe outer face of the ring 23 and similar adjusting members 27 arethreaded to the collar 24'and bear against the outer face of the ring25. I

Inassembling the impressionroll the collar 22 withits ring 23 andadjusting members 26 is first mounted upon the hub 11 in the positionshown in Fig. 1 of the drawings. The cylinders 17,18, and 19 are thenplaced upon the arbor 10 with the key 16 in'tthe key-Way'14c." Thecollar 24 is then threaded to the hub 12 and the members 27 adjusted toforce the ring 25 against the adj aeent end of the cylinders 17, 18,and'19 to force said cylinders firmly against the inner face of thering23. I The collar 24 is then rotated about the hub 12 until itassum'es aposition indicated in Fig. 1 of the drawings.

When it is desired to remove the cylinders 17, lsgand 19 from the arbor10, the'collar 2a with the parts mounted thereon is rotated about'thehub. 12 until in the position shown in Fig. 30f the drawings. Theadjusting members 26 arethenrotated' to move the ring 23 away fromtheflanged portion of the'collar' 22, thus forcing the cylinders '17,18',and 19 into theposition indicated in Fig. 3 of the drawings; If thenthe collar 24 and the partSMmOunted thereon are removed fromthe-threadedhub 12, the cylinders 17,

Copies of this patent may be'obtained for any flat material. Theseimpressions in the flat material may be of regular or irregularformation, as desired.

It is believed that the operation and many advantages of this inventionwill be fully understood from the foregoing description,

We claim: 7

1. An impression roll having a plurality of peripheral projections ofdifferent heights and lengths and of varying thickness.

2. An impression roll consisting of a cylinder'having peripheralprojections, a tubular support therefor having a tapered bore, aconeshaped arbor on which said tubular support is mounted, flangethreaded to and movable lengthwise of said arbor for positioning saidsupport thereonyan annular plate on the inner face of said flange,'andmembers threadedto said flange and'bearingagainst said annular plate.

3. An impression roll consisting of a cylinder having peripheralprojections, atubular support therefor having a tapered bore,aconeshaped arbor on which said tubular support is mounted, a flange onsaid arbor, a plate movable on said flange, and members threaded'to saidflange and bearing against said annular plate. 4:. An impression rollhaving a plurality of peripheral projections of differentheights,"lengths and thicknesses separated by portions in the samecylindrical plane and 'alined lengthwise of said-roll.
